Dr. Merkin has 15 years of experience in numerical modeling of space plasmas, in particular, magnetohydrodynamic (MHD) simulations of the earth’s magnetosphere and inner heliosphere. He has been deeply involved in the development of the LFM MHD model of the global magnetosphere, its regional magnetotail (LFMBOX) and heliospheric adaptations (LFM-helio). He is the primary author of the MIX simulation code which mediates magnetosphere-ionosphere interactions within the LFM model. His work on the development of space plasma simulation codes, and coupling between different physical regions and regimes, has spanned the domains from Earth’s ionosphere, to the magnetosphere and solar wind. Dr. Merkin has been an active member of the space science community: the simulation models he has developed are available through the Community Coordinated Modeling Center to a wide range of scientists; he has served as a Research Area Coordinator for the Geospace Environment Modeling community; and regularly serves on review panels.
